Wouldn't it be cool if, when a piece of Tier drops for you, in personal loot, if you could still trade it to people that share the "token" and the tier piece changes to their spec? Had a situation last night where the tier cloak dropped and both paladins and the warlock didn't need it, yet here I was as the lone demon hunter and could have used it.
I think it would be neat to be able to trade the personal-loot tier and have it change.
